The exhaust manifold, generally indicated by the numeralS, may bemounted upon one side of-tho block of engine e \"lin'ders in anypreferred manner. This exhaust manifold -is suitably connected to theexhaust ports. as indicated at 9, and is provided with .an upperlongitudinally extending compart- -ment 10"and the lower'eompartment I.These coi'npartments' of the exhaust manifold are separated by alongitudinally extendingwall 12. 'Adjacentto one end of the uppercompartment l of the exhaust manifold, an inlet chamber 13 is provided,to

This heatedminture will also heatthe pipe 19and the. water contained therein. As the l "pand as it is not" desirableto heat the in.-

terior. ofjthe manifold above a certain degree, say '150.1,' at-whichtemperature the kerosene vapors would become separated or dissipated sothat a. good combustible m1X v turewould not be obtained. Upon the ex--pansion of this water-filled tube 21, the contact is moved away from thecontact '28 and the electric circuit-is broken.v This end ofsaidtubewill almost immediately engage with the valve stemv 21. and opens theair intake valve '20sathatatmosphric air may enter the inlet manifold,thereby reducing theteniperature of the, same. :Thus, the

gaseous mixture passing through the intake manifold ismalntalned at aconstanteven temperature. I have found ln'actual practice that, by theprovision "ofthe flat tubes or conduits 16, the kerosene is thoroughlyvaporiz'ed, as an extensive surface is afi'orded withwhich the'exhaustgases from the err: gine cylinders may contact. By the provision' inaddition, of the electrically heated chamber, passes through'the'severa-l' pipes .16. The exhaustfrom theenginecylinders highlyheated burned gases with these pipes,-

rod extending intothe intake manifold, the .possibility of solid'orunvaporized constit- 'haust and-intake manifolds as shown, and

. tensive surface exposed to the exhaust gases, the mlxture willfirst beheated to a hi 11 so that, by the additional heating of the intakemanifold through the medium of the electrically heated tubular rodextending within thefsame, the inadequacy of vaporizers of this typeforthe purposeof utilizing the lower grades'of hydro-carbon fuels, is

overcome. throughthe lower compartment 11 of the manifold are exhaustedthrough the ordiln'ary'mufiler to the'atmosphere. v r

-ing, it is believed that the construction, manner of operation, andseveral advantages of the invention will be clearly and a fullyunderstood. The device, while exceedingly simple. in its construction,has been found by repeated tests'to b highly rially reduce the operatingcost of motor .vehicle engines by the use of a low grade hydro-carbonfuel'such as kerosene which is relativelyinexpensive. I have alsodemonstrated that, by means of the present invention, kerosene may beused as fuel without any reduction of power over thatqobtained by theuse of gasolene, and in some instances .the power obtained was evenincreased. In

it will, of course, be understood that the manifold construction, aswell as the mounting and arrangement of the electrically .heated tubeand the expansible circuit closer and valve opening device maybe changedas desired, in accordance with the particular type of engineupon whichthe device is to be employed. I, therefore, reserve the privilege ofadopting all such legitimatemodifications as may be fairly embodiedwithin the spirit and scope of the invention as claimed.

Having thus fully described my invention, what Idesireto claim andsecure by Letters Patent is;:

The combination with an internal combus tion engine having intake andexhaust ports, of 'anexhaust manifold having upper and lowercompartments, said upper compare. ment-being'connected to the exhaustports,

said manifold being provided with an inlet chamber at one end of theupper c0mpart ment; a intake manifold centrally] located within thelower compartmentand connect ed tothe intake ports of the engine, and 1aplurality of transversely elongated con: dil it's in communication stoneof their ends 'with vsaid inlet I chamber and extending through. theupper compartment and into,

said conduits being connected to the intake manifold. v
